Clock syncrhonisation limits in a cluster?
We have a cluster of eight nodes, where clock synchronisation through ntpd has not been working well and clocks have been getting out of sync. I know the fix is to fix the clocks, we are on it.... but does anyone know what the absolute limits are for discrepancies in the system clocks, of nodes in a cluster?

According to the vnetperf optimization tool, it is recommended to keep the clock skew < 1 second.

Thanks for this! Sorry, read it at the time and it was useful and then got caught up in other problems.
